Submersible motor pump systems as complete solution
RheinHunsrück Water association upgraded the first of its 8 wells of water work RheinHunsrück to the new technology with permanent magnets.
The capacity of the aquifer varies depending on the season. Therefore the pumps have to adapt to different delivery heads. This is ensured by the frequency regulation. In addition, the oddesse submersible pump secures at a maximum delivery head of 31.5 m a flow rate of 70 l/s at a power input of P2 = 26.5 kW and up to 83 l/s at a power input of P2 = 32.4 kW. An appropriate system, consisting of a 10 inch submersible pump po-ss-270-1/10.1 with a 6”-permanent magnet-synchronous-motor po-mo-s6.2x 45 kW having a power input PN from 30 to 45 kW, and a frequency converter with du/dt filter, was provided to the water works. To the satisfaction of the operator both duty points can be run with this same system. A first evaluation showed that the energy consumption of the well could be reduced significantly. Before, the delivery of 1 m³ water required 0.1304 kW. The new system results in a consumption of only 0.0918 kW/m³, accounting for an energy saving of 0.086 kW/m³. For a delivery head of 70 l/s, 9.65 kW/h can therefore be saved. With a continuous use of the pump of 8,000 operating hours per year, 77,200 kW and nearly 17,000 Euro on energy costs could be saved.
You can find the catalogues for 6“- and 8“-permanent magnet-synchronous-submersible motors on our website.
At the moment oddesse is working to use submersible motor pumps with permanent magnet motors for the recovery of energy. In several cases water from high-elevated tanks is fed with high operating pressures in pipelines and is adapted to the water supply pressure by using a pressure regulator. This energy shall then be used for the self-consumption of water suppliers.
Visit us for example at Trinkwassertagung Paderborn on 27 and 28 September or at Energie- und Trinkwassertagung ETWT on 24 and 25 October in Hawangen. We would also like to welcome you at Meistererfahrungsaustausch in Lübeck-Travemünde in December.
Permanent magnet-synchronous-submersible motors in use
By replacing an asynchronous by a synchronous motor, the operator of the waterworks in Colbitz, Germany, could reduce the annual energy consumption of one well by approx. 24,500 kWh and could therefore save 3,900 Euros.
By the way – the German government initiated a fund to support the replacement of old and inefficient pumps and motors. Maybe other governments offer similar financial support.
Solids in waste water – No problem for ORCUT TES!
– Yet, that is no problem for the ORCUT TES. Unlike other waste water pumps ORCUT TES has a conical triple cutting system, which really gives a scissor-like cut of these solids without any problems.

Review Wasser Berlin International 2017
At our booth you were able to see our new submersible motor pump systems with permanent magnet-synchronous-submersible motor. Furthermore the proven submersible motor pumps, asynchronous motors, drainage, propeller as well as sewage pumps encountered the interest of our visitors.
Energy efficient submersible motor pump system
The system, consisting of a submersible motor pump with permanent magnet motor, frequency converter and output filter are already successfully used by some of our customers. Due to the permanent magnet technology and the matched components the overall efficiency of the system can be increased by up to 9 % and energy costs can be reduced by 30 %.
The permanent magnet-synchronous-submersible motors are available in 6“, 8“, and 10“ size. You can find more information regarding our permanent magnet motors here.
The development of the Permanent magnet-synchronous-submersible motor is supported by the European Union with funds of the European Fund for Regional Development (EFRE).

Coupling fitting for difficult applications
Through a coupling fitting two or more pumps can be easily connected in series. Thus, the discharge head of the pump can be increased and the flow rate remains constant. The coupling fitting is installed directly at the suction piece of the second pump and is available for the entire Söffel-series.
We have been able to significantly extend the application range of our slim and extremely robust drainage pumps through the coupling fitting.
In addition, we also have other accessories available for you. For example low-level suction fittings for Söffel-pumps make it possible to lower the water level down to 8 mm.
The three-year apprenticeship as electronic technicians for industrial engineering is provided in cooperation with the eductaion center of Avacon AG.
We wish both of them a good start and much success.
Review IFAT 2016
At our booth you were able to see our recent developments and capabilities. Beside the proven submersible motor pumps and submersible motors, sewage and drainage pumps the recent developments regarding our submersible motor pump systems with permanent magnet-synchronous- submersible motor encountered the interest of the national and international trade visitors.
A total of 3,097 exhibitors - 1,695 companies from Germany and 1,402 companies from other 59 countries, presented their innovations and new developments for the environmental technology sector on 230,000 square meters of exhibition space. With 45 percent, the proportion of exhibitors from outside Germany was higher than ever before at IFAT.
10th anniversary of ORPU Pumpenfabrik GmbH
The company Hellfrich Oranienburg was founded in the year 1936. The VEB Metallwerk, which consisted of several companies, was transformed to Oranienburger Pumpen-, Verdichter- und Maschinenbau GmbH in 1990.
After the acquisition of the insolvent company, the subsidiary of oddesse has been operating as ORPU Pumpenfabrik GmbH since March 2006.
For over 80 years, the company has been developing and producing pumps and compressors. The product range includes pumps for delivering clean and waste water, sewage lifting systems as well as compressors for ventilation of biological treatment plants.
Use on Board
The ORPU-sewage pumps ES, KM as well as side channel and submersible motor compressors are used on board and on offshore platforms for the treatment of waste water. The propeller pumps po-upl, the drainage pumps po-Söffel and the submersible motor pumps po-so/ss in particular are highly qualified for different systems for the delivery of sea and brackish water.
All products are certified in accordance with DNV GL - Maritime or ABS, two of the biggest and international accepted ship and offshore classification societies.
Energy efficiency - the measure of all things, for us as well
They work intensively to reduce the life cycle costs of pumps. With a share of 80 % the energy costs are an essential factor for the profitability assessment.
For us as a manufacturer it is therefore important to provide pumps and motors with high efficiencies and to adapt the pumps to the required parameters. For our submersible motor pumps we are going an unorthodox way. By precisely adapting the impeller diameter to the operating parameters, we adjust the pump hydraulics and demonstrate the results in a test report. At constant operating parameters, this procedure offers an alternative solution to the speed control in pumps. The investment costs can be reduced.
In this way we were able to attract new customers.
If you want to make your pump system more efficient or want to get further information we will provide you with advice and assistance.

Hot water installation in Indonesia
These operating temperatures put high requirements on the construction of submersible motors. So there is considerable demand on the winding of the motor and on the sustainability of used bearings.
So far other motor manufacturers have been unable to offer reliable solutions for that purpose.
By combining a 6" submersible motor pump with an 8" hot water submersible motor at a voltage of 1000 V, we are able to minimize the default risk of overheating.
Thanks to our Australian partner, the oddesse submersible pumps have been successfully in use in the Gosowong mine since October 2013.
We implemented a similar project for our customer in Vietnam, too.
Pumps and motors put to the test
Here up to two submersible pumps can be tested computer-aided at the same time. The maximum drive capacity is 400 kW at 50 Hz.
The test tank, inserted in the hall floor, with well imitations is 6.50 m deep, holds 300,000 litres of water and allows the installation of submersible pumps up to a length of 5m.
Flows from 3 to 2500 m3/h and heads of up to 400 mWS can be simulated from the central evaluation and operator station.
Apart from testing oddesse products, we offer our customers the testing of pumps and motors from other manufacturers, as well. The highlight is that we adapt the duty point of the pump according to customers’ needs. The results are automatically recorded, printed on a report and handed over to the customer.

Vessel damage control pump
At a flow rate up to 77 m³/h and a delivery head of up to 45 m, the pump has a maximum nominal power of P2 = 7.5 kW.
The pump meets all ergonomic requirements for the use on ships. The weight of 60 kg is not exceeded, so that a transport by two persons can be realized. An additional grab handle on the pump bottom secures the option for horizontal transport and the safe stand of the pump. In addition, a sling point (eye bolt) on the discharge side allows the abseiling of the pump. The suction side has a special construction. The integrated strainer of the pump is provided with a Storz connection B and can therefore be easily removed when the pump is to work in tandem installation. The revolving pedestal protects the strainer as well as the coupling fitting in the respective application.
The constructive solutions can be applied to the entire series of submersible drainage pumps Söffel.
Review WASSER BERLIN INTERNATIONAL 2015
Our exhibition stand, which was constructed by the company M3 from Magdeburg, left a very good impression on the visitors.
Beside the proven submersible motor pumps and submersible motors, sewage and drainage pumps the new bottom intake pumps and vessel damage control pumps encountered the interest of the national and international trade visitors.
Overall, we can look back on a successful exhibition with many constructive discussions. The numerous trade reports are being evaluated and processed by us now.
We are hoping for an equally strong response at IFAT 2016 in Munich and are looking forward to seeing you there.
Thank you very much for your visit.

Milestones – oddesse celebrates anniversaries
This was the birth of the pump industry in the Magdeburg region. A merger in 1897 brought the current company name from Hamburg to Oschersleben. The Maschinenfabrik oddesse GmbH was founded. With the development and production of submersible motors and submersible pumps at the end of the 1930s the path was laid for the oddesse pump and motor factory as it is known today.
In September 2014, oddesse will celebrate this anniversary together with many customers, partners and employees.
